Glastonbury Tor Startrails

Glastonbury Tor is a hill at Glastonbury in the English county of Somerset, topped by the St Michael's Tower.
The Tor seems to have been called "The Isle of Avalon".
According to King Arthur's mythology, Avalon is where his sword Excalibur was forged.
This is a wide field photo from a full frame camera and a 14mm lens, showing the Polaris, the Northern Star to the upper left and the celestial equator to the right of the image. Selecting a combination of relatively low ISO, small aperture and long exposures I managed to illuminate the foreground using only the ambient light, retaining the star colours.
The only side effect was that I had to withstand strong wind and temperatures below 0 °C for a considerable amount of time, completely still and lightly dressed until I get this nice pose.
No, I didn't stay there during the whole two-hour shooting, but just a few two-minute exposures where enough for never underestimate the British weather conditions again!
